I applied Fleuriot Damien's values to /boot/loader.conf and yours to the smb.conf. Somewhere in the handbook this should be documented! it is to much efford to get SAMBA working properly with ZFS, if the tricks and problems are so widespread over several architectural aspects of the syst= em. It could save a lot of time for adminsitartors and those which try FreeBSD as a serving system instead of Linux. Just for the record. I feel a bit confused about all the tricks and tweak now "published" for ZFS, its magic L2ARC, the kernel_vmem wizzardy thingis. The ZFS Wiki seems to be a bit outdated and confusing, it would be a great deal if all these things could be lined up a s a primer with a bit more explanations than "put this number there". And by the way, it is like changing from hell to heaven having now ~ 100 MB/s throughput compared to ~1/500!
